4株放线菌对柱花草促生作用的测定

采用皿内测定和盆栽实验测定4株放线菌的发酵液对柱花草幼苗形态指标(鲜质量、株高、茎长、根长)和生理生化指标(叶绿素含量、可溶性蛋白含量、可溶性糖含量、根系活力)的影响,探究供试菌株对柱花草的促生作用.实验结果表明,4株放线菌发酵液在一定浓度下均可促使幼苗鲜质量增加和茎的伸长,提升柱花草的株高,增加植株叶绿素、可溶性蛋白...

Determination of the Effect of Four Strains of Actinomycetes on the Growth of Stylosanthes

Stylosanthes were cultured on culture dishes, pot cultured and then inoculated with fermentation broths of 4 strains of Streptomyces spp, one of the genus of Actinomycetes., to observe tTheir growth were observed h, and their morphological indexes (fresh weight, plant height, stem length and root length) and physiological and biochemical indexes (chlorophyll content, soluble protein content, soluble sugar content and root activity) were determined. The results showed that the fermentation broths of the four strains of Streptomyces spp. increased the fresh weight, stem length and plant height as well as the contents of chlorophyll and soluble protein of the seedlings of Stylosanthes. In general, the four strains of Streptomyces spp had an obvious effects on promoting of the growth of Stylosanthes, and improved the quality of Stylosanthes to various degrees. These results, which indicates that Actinomycetes can be used to increase the yield of Stylosanthes.
